Find no of time a character used in string using PHP 

  1. function char_in_string($string){
  2.  $char_array=str_split($string);
  3.  for($i=0;$i<sizeof($char_array);$i++){
  4.    $no_of_char[$char_array[$i]]=0;
  5.    for($j=0;$j<sizeof($char_array);$j++){
  6.      if($char_array[$i]==$char_array[$j])
  7.      {
  8.        $no_of_char[$char_array[$i]]++;
  9.      }
  10.    }
  11.  }
  12.  return $no_of_char;
  13. }

 

Now show its structure using var_dump()

var_dump(char_in_string("Hello Ahmad Asjad"));

Its result will look something like this.

array (size=12)
  'H' => int 1
  'e' => int 1
  'l' => int 2
  'o' => int 1
  ' ' => int 2
  'A' => int 2
  'h' => int 1
  'm' => int 1
  'a' => int 2
  'd' => int 2
  's' => int 1
  'j' => int 1
